Bush cucumbers

Hello.

I'm growing bush cucumbers for the first time and wanted to know if I should stake them or not.  The seed packet doesn't mention it but they seem to be wanting to creep along the veg patch instead of growing into a bush

I grew some last year and they did spread sideways a bit like some courgettes do, but they don't spread far.
I didn't bother with a cane just left 'em to get on with it
